ABB Cylon Aspect 3.08.02 (ethernetUpdate.php) Authenticated Path Traversal
Vendor: ABB Ltd.
Product web page: https://www.global.abb
Affected version: NEXUS Series, MATRIX-2 Series, ASPECT-Enterprise, ASPECT-Studio
Firmware: <=3.08.02
Summary: ASPECT is an award-winning scalable building energy management
and control solution designed to allow users seamless access to their
building data through standard building protocols including smart devices.
Desc: The ABB Cylon controller suffers from an authenticated path traversal
vulnerability. This can be exploited through the 'devName' POST parameter in
the ethernetUpdate.php script to write partially controlled content, such as
IP address values, into arbitrary file paths, potentially leading to configuration
tampering and system compromise including denial of service scenario through
ethernet configuration backup file overwrite.
